我们可以在swift中混合数组中的类型吗？

Question

在Swift 3游乐场中，我想创建一个可变数组，其中包含一些索引处的数字和其他索引处的字符串。我这样做会出错：

var playerInfo = [[String]]()
playerInfo[0][2] = "Adam" //Error: Execution was interrupted, reason: EXC_BAD_INSTRUCTION (code=EXC_1386_INVOP, subcode=0x0)
playerInfo[0][3] = "Martinez"
playerInfo[0][1] = "00"

编辑： 像这样的东西？

var playerInfo: [[String:Any]] = [
     [
     "playerNumber" : "00",
     "playerFirstName" : "Adam",
     "playerLastName" : "Martinez"
     ]
]

Answer 1

您没有正确使用语法。

试试这个：

var playerInfo = [[String]]()
playerInfo.append(["00","Adam","Martinez"])

修改

对于您的编辑，您需要一个词典：

var playerInfo = Dictionary<String, Any>()

playerInfo["playerNumber"] = "00"
playerInfo["playerFirstName"] = "Adam"
playerInfo["playerLastName"] = "Martinez"
